본 연구의 목적은 여자 대학생 태권도 선수들의 선수 경력, 대회 참가빈도가 운동몰입에 미치는 영향을 분석하는 데 있다. 본 연구의 대상은 여자 대학 태권도 선수 20명이다. 선수 경력과 대회 참가빈도 는 4점 척도로 조사하였고, 1점에서 4점으로 점수가 높으면 높을수록, 선수 경력과 대회 참가빈도가 높음 을 의미한다. 운동몰입에 대한 평가는 운동몰입척도를 활용하였다. 운동몰입척도는 총 8문항으로 행위 몰 입 4문항과 인지 몰입 4문항으로 구성되어있고, 5점 리커트 척도를 활용하여 평정하며, 점수가 높으면 높 을수록 운동몰입 수준이 높음을 의미한다. 그 결과 대회 참가 빈도와 운동몰입 간에 정적 (+) 상관관계와 인과관계가 나타났다. 선수 경력은 부적 (-) 인과관계를 보였다. 이러한 결과는 대회 참가빈도가 높을수록 운동몰입 수준이 증가하며, 선수 경력이 길수록 운동몰입 수준이 감소한다고 설명할 수 있다. 따라서, 여자 대학 태권도 선수들의 운동몰입 수준을 향상시키기 위해 대회 참가 빈도와 선수 경력을 고려해야 할 것이 다.
Physical therapists have been using balance and weight shifting training to induce improvements in standing and walking. This study compared the effects of kinetic feedback frequency and concurrent kinetic feedback on the performance and learning of a weight shifting skill in young, nondisabled adults. Sixteen young adults without known impairment of the neuromusculoskeletal system volunteered for the study. Subjects in each of three kinetic feedback groups performed a weight shifting task in an attempt to minimize error between their effort and a center of pressure (COP) template for a 12 second period. Feedback was provided: 1) concurrently (concurrent feedback), 2) after each trial (100% feedback), 3) after every other trial (50% feedback). Immediate and delayed (24 hour) retention tests were performed without feedback. During acquisition phase, the concurrent feedback group exhibited less error than either of the post response feedback group. For the immediate retention test, the 50% feedback group exhibited less error than did the 100% feedback and concurrent feedback. During the delayed retention, 50% feedback group displayed less error than did the other groups. But no significant differences were found between groups. These results suggest that practice with concurrent feedback is beneficial for the immediate performance, but not for the learning of this weight shifting skill. Lower frequency of feedback resulted in more permanent changes in the subject's ability to complete the task.
Several studies have evaluated the effects of types of relative frequency and delay interval of knowledge of results(KR) on motor skill learning independently. The purpose of this study was to determine more effective types of KR relative frequency and KR delay interval for motor learning. Forty-six healthy subjects (15 female, 31 male) with no previous experience with this experiment participated. The subjects ranged in age from 20 to 29 years (mean=23.9, SD=0.474). All subjects were assigned to one of four groups: a high-instant group, a high-delay group, a low-instant group, and a low-delay group. During the acquisition phase, subjects practiced movements to a target (400 mm) with either a high (83%) or low (33%) KR relative frequency, and with either an instantaneous or delayed (after 8s) KR. Four groups were evaluated on retention (after 3min and 24hr) and transfer (450 mm) tests. The major findings were as follows: (1) there were no between-group differences in acquisition and short-term retention (p>0.05, (2) a low (33%) KR relative frequency during practice was as effective for learning as measured by both long-tenn retention and transfer tests, compared with high (83%) KR practice conditions (p<0.05), (3) delayed (8s) KR enhanced learning as measured by both long-term retention and transfer tests, compared with instantaneous KR practice conditions (p<0.05), and (4) there were no interactions between KR relative frequency and KR delay interval during acquisition, retention, and transfer phases. The results suggest that relatively less frequent and delayed KR are more effective types for motor learning than more frequent and instantaneous KR.ㅂ
이 연구의 목적은 자기평가체형과 체력수준 및 운동빈도가 중학생의 사회적 체형불안에 어떠한 영향을 미치는 지를 알아보는 것이었다. 연구 참여에 동의한 남녀 중학생 총 410명(남: 194명, 여: 216명)이 배경정보를 묻는 설문지와 자기평가체형검사지 및 사회적체 형불안검 사지에 자기평가기입 법으로 응답하였다. 자료처리는 PASW 18.0 통계프로그램을 이용하여 독립 t-검정과 다변량 분산분석(MANOVA)을 실시하였다. 통계분석 결과, 중학생들의 사회적 체형불안은 성별(p<01), 비만도(p<001), 체형왜 곡정도(p<01), 자기평가체형(p<001), 체력수준(p<01), 및 운동빈도(p<01)에 따라서 유의한 차이가 나타났다. 연구결과를 통찰할 때 학생들의 올바른 신체상 정립과 사회적 체형불안을 감소시킬 수 있는 교육프로그램 개발의 필요성이 시급히 요구된다.
